test e / Finasteride ???

Im about to start and 10weeker of test e at 400 a week, I have been on the liquid finasteride a little over a month. When i start the cycle i plan to up the finasteride dosage to 2mg. MY question is will this be enough to combat losing hair? I have been shedding for the last month a little bit, from the finasteride. Will the extra test from the cycle fcuk up the the process that is going on with the finasteride,fall out then regrow, is what im talking about,thanks in advance bros
